v UNITED STATES PATENT OFFICE GUSTAV EGLOFF, OF CHICAGO, ILLINOIS, ASSIGNOR T UNIVERSAL OIL PRODUCTS COMPANY, OF CHIOAGQILJQINOIS, A CORPORATION OF SOUTH DAKOTA J ArrAnArus' 'FOR "convnnrrne HYDROGARBONS Application filed June afie'a'ifseriar nah 5,242.." Renewed February 21, 1929.

This invention relates to improvements apparatus for converting hydrocarbons and refers more particularly toanapparatus for converting relatively highboiling pointoils to oils of lower boiling point having the characteristics of gasoline and the like.

. Among the salient'objectsof the invention are to provide an apparatusinwhich-the raw oil treated may be combined with regulated quantities of reflux and residuum and the mixture charged to thefiheating zone to be'raised to a conversion temperature; to

provide an apparatus in which the vaporized portions of the oil from the expansion chamber are dephlegmated and condensed, the reflux condensate from the dephlcgmating zone being collected asis the residuum or unvaporized portion from the expansion chamber ,in separatetanks; to provide an apparatus in which regulated quantities of the raw oil,"

reflux and residuum may be withdrawn from these separate reservoirs or tanks and intro.-

duced to the charging line or any desired combination of these oils may be charged to the heating zone as desired. The single figure is a diagrammatic sideelevational View of the apparatus.

Referring in detail to the drawing, the oil to be treated is introduced through the charging line 1 controlled by a valve 2 into the pump 3 which forces the oil into a' raw oil reservoir 4; A dra'wofl' line 5- controlledby a valve 6 from this tank or reservoir connects with the inlet line 7 to the heating tubes 8 mounted in the furnace 9. The oil,

after being heated to a cracking temperature I passes to the expansion chamber 10 to which are connected the'vapor line 11 controlled by valve 12 and the residuum line'13 regulated by a valve 14:, the latter directing the residuum to a tank 15. The residuum collected in the tank 15 may be withdrawn through the line 16 regulated by a valve 17 and passed toseparate storage tanks or it may be With- 'd'rawn through the line 18 controlled by a 50 through the vapor line 11 are refluxed in the dephlegmator 20 from which they pass over to the line 21 to the water condenser 22 and thence to a receiver 23 where they may be drawn from the system through the valve 24. Pressure relief valve 25 and pressure gauge 26 are fitted to the receiver. The reflux oil from the dephlegmator passes down through the line 27 controlled by a valve 28 into the reflux tank 29. where it is collected and may be drawn off to separate storage through the line 30 controlled by a valve 32 or may be directed through the'line 33 regulated byv a valve 34 and reintroduced to the inlet line 7 in regulated quantities with the'raw oil and residuum drawn from the tanks 4 and 15. It is, obvious that by collecting the raw oil, reflux and residuum in separate storage tanks of the type shown,' and that by drawing off regulated quantities 1. In an apparatus for converting hydrocarbon oils, the combination with means for heating and vaporizing the oil, of dephlegmating and condensing means connected thereto, means for collecting separately the reflux condensate from the dephlegmating means and the residual products from the vaporizing means and means, comprising valves for controlling the outlets from the collectingmeans for the reflux condensate and the. residual products, for introducing said reflux and residual products in regulated quantities with the oil to be treated to the heating means.

2. In an apparatus for converting hydroa carbon oils, the combination with means for raising the oil to a cracking temperature comprising a heating coil, of a vaporizing chamber connected thereto, dephlegmating and condensing means connected with the vaporizing chamber, means fer collecting separately the residual oil from the vaporizing chamber and the refluxv condensate:

from the dephlegmating means and alternate drawofl' lines from sai collectingmeans for directing the residuum-and re flux back to the heating means or for directing said products tostorage.
